I believe most of the regular 6.2L F150's come with the 3.55 and 3.73 gears and the 4.10 E locker was an option.
Maybe that's the reason for different gear oil weight?

Ford does state in the regular 2014 F-150 manual that 75W-140 in the rear. But actually if you look at the 2014 Raptor Supplement owners manual, Ford changes it to 75W-85. I checked some of my workorders as the dealership has opened my rear end several times, they used 75W-140. I will say something next time it needs to be opened.
I don’t see his concern. He stated a fact and asked a question. Exactly what these forums are for. Didn’t warrant your response.

Actually this is a Raptor forum to ask questions about the Raptor...That is the purpose of this forum. Because his question wasn't about the Raptor he got the response he did...not so hard to understand
Wow, I really didn't mean anything by my comment, wasn't trying to be sarcastic or rude.
It's know that the Cams and Tuning makes the difference between the three 6.2L.
Are there any other differences that Ford has made would be hard to find out.
They could have made the oil squirters slightly larger to accommodate the heavier weight oil.
Just guessing though.
I did a quick research and found talk about using oil squirters to cool the pistons.
There is a debate about to much oil, too high of an oil pressure and too heavy of an oil can compromise the ring seals.
Too much and the rings do not seal solidly against the wall, creating a lot of blow-by.
Then there are guys that remove them and/or close them up to get the most seal for highest compression.
Sounds good but then your looking at rebuilding the engine more often.
My previous comment was not directed to you. There may be some slight differences between the 6.2L V8s, but to act like my question has no relevance to a Raptor is nonsense. Ford built the Gen 1 on the SD powertrain platform.
There was a guy I found on a SD forum that was running 5W-30 on either his 12 or 13 6.2L V8 SD. He got over 400k miles before one of his cam shafts went bad. In other words, he started running 5W-30 years before Ford ever made the official switch and got 400k miles with regularly towing.
I agree with you that one has to be careful when switching oil weights. But in this case, I think it is at least probable to move to a 5W-30 and have little to no effect on the engine. Given that Gen 1s are rated for fuel economy, I am sure having a more fuel efficient engine oil influenced—at the very least played a part—in why Ford chose 5W-20. Also, some Livernois 6.6 owners that I have talked to have moved to a heavier oil weight too.
"Essentially" is the operative word and words matter.Can you not read? The 6.2L V8 is essentially the same in the Super Duty and Gen 1. Stop acting like a moron.
